UPD78F9116B Overview
The µPD78F9116B is a µPD789114A Subseries product of the 78K/0S Series. The µPD78F9116B replaces the internal ROM of the µPD789111A,789112A and 789114A with flash memory, which enables the writing/erasing of a program while the device is mounted on the board. A stricter quality assurance program (called special grade in NEC’s grade classification) is applied to the µPD78F9116B(A), pared to the µPD78F9116B, which are...
